STEAM-ENGINE.

SPECIFICATION forming part of Letters Patent No. 516,064, dated March. 6, 1894.

Application filed July 15,1893.

To aZZ whom it may concern:

Be it known that I, EUGENE Snroncxnn, a citizen of the United States, residing at San Jose, Santa Clara county, State of California, have invented an Improvement in Steam-Engines; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to certain improvements in steam engines, and it consists in certain details of construction which will be more fully explained by reference to the accompanying drawings, in which- Figure 1 is a plan view of my engine. Fig. 2 is a cross section through the boiler furnace. Fig. 3 is a cross section through one of the reactionary wheels and casing on line y of Fig. 4. Fig. 4: is a cross section through the casing on line sc-0a of Fig. 3. Fig. 5, is a horizontal section through the cylinder E on the line w-w of Fig. 6. Fig. 6, is a vertical section through the valve chest of the cylinder E on the line 2-5 of Fig. 5.

The object of my invention is to combine in a single apparatus mechanism for utilizing the steam directly from the boiler in an initial high pressure cylinder, exhausting it into a second cylinder where it is also utilized to drive a piston,which in turn acts on its return stroke to pump the steam into a super-heater from which it is again delivered to a third cylinder where it acts upon the piston, and thence passes into a reactionary wheel mounted upon the same shaft, and thence is exhausted. In the present case I have shown only such portion of an engine as is necessary to illustrate the novelfeaturesof myinvention.

A is a crank shaft upon which are fixed the cranks B, G and D at such angle with each other as to apply the power as nearly continuous as possible.

E is the initial high pressure cylinder, receiving steam from the boiler at e and from this cylinder the steam is exhausted into a cylinder G. Within this cylinder is a reciprocating piston which connects with the crank D, and the inlet pipes from the cylinder E are so arranged that whent'he steam exhausts from one end of the cylinder E, it passes through a pipe II and enters the cylinder G upon one side of the piston, thus acting to Serial No. 480,667. (No model.)

force the piston to the opposite end of its stroke. When the piston in the cylinder E moves in the opposite direction, the steam is exhausted through the pipe I upon the other side of the piston in the cylinder G, thus reciprocating it in the opposite direction from that first described. Each end of this cylinder is connected with a super-heater J by pipes or passages K and L as shown. These passages are controlled by valves which are positively operated from the crank shaft or other moving portion of the apparatus, so that after the steam has been utilized in the cylinder G to drive its piston to one end of the stroke, the valve connecting with the cylinder upon that side is opened, thus allowing the steam to pass from the cylinder into the super-heater when the piston makes its return stroke, and it then acts in the capacity of a pump to force the steam into the super-heater. The super-heater J is situated within the boiler furnace in any suitable relation with the furnace and within the boiler setting, as shown, so that the steam admitted thereto will be heated to a higher temperature, and it is then delivered through a pipe 0 into the engine cylinder P, the piston of which is connected through the usual piston and'connecting rods, with the crank B of the shaft A. By thus utilizing the super-heater intermediate between the second and third cylinders I raise the temperature of the steam which has been considerably reduced by its expansion, and render it more elastic before it enters the third cylinder. From the third cylinder P, the steam is exhausted, passing through the pipes Q, and B into a compartment chamber S from which it is delivered into a case T within which are the two wheels U and U.

These wheels are fixed upon the shaft A and are provided with buckets V so arranged that the steam is delivered alternately from the exhaust pipesQ and B into the buckets of first one wheel and then the other. These buckets are so arranged with relation to the exterior casing within which they rotate that the steam acts first directly to impel the buckets and then escaping out rearwardly through the passages W it has a reactionary effect, and this assists in propelling the wheel. From this point the steam escapes either to a condenser or directed to the open air if desired.

In Figs. 5 and 6 I show one set of cylinders only as the construction is well known, but it will be understood that the other cylinders will be provided with steam chests and slide valve similar to those shown insaid figures.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In an engine, the cylinders E, G and P, the super-heater J, pipes by which the steam is exhausted from the first t0 the second cylinder, valves connecting the second cylinder with the super-heaterthrough which the steam is discharged from the second cylinder into the super-heater, apipe connecting the superheater with the third cylinder, and pipes through which the exhaust steam from the third cylinder is delivered to the buckets of hand.
